## Description

SLOW-CURE 30 min. epoxy works best for forming reinforcing fillets on joints. It has the highest strength of our epoxies. It is waterproof and more heat resistant. SLOW-CURE can be used for bonding if you’re willing to wait overnight. Fillers such as micro balloons can be mixed with SLOW-CURE and FINISH-CURE to form a putty-like consistency. Such fillers will usually decrease the working time by about 25%. Bonded objects can be handled after 8 hours and the cured epoxy reaches full strength within 24 hours. Directions in 5 different languages.

## Questions & Answers

**Q: Can I use this Epoxy for adhering stones for jewelry**
A: Yes, but it will tend to not work as well for larger stones glued to flat surfaces. My wife makes glass jewelry and swears by E6000 silicone

**Q: Is the consistency runny enough to use for sealing the end grain of exterior wood?**
A: I haven't tried it for sealing end grain.  That said, I would expect it to work.  Just watch your cure time; the BSI-205 gets an initial set after some 30 minutes, but may need 12 or more hours to develop a full set.  Double-check the instructions for set time.

**Q: Does this bond metal and wood together?**
A: Yes it will bond wood and metal together.  Works best when either material is scuffed up a bit. 
Russ-Pen Kit Mall

**Q: Can this be use for filling dings on electric guitar basses? Can it then be sanded down to mirror like finish?**
A: Epoxy can be used to fill dings on almost anything. Epoxy can be sanded once it's cured. To get a mirror-like finish might require some kind of coating- paint, polish? Good Luck!

### ⭐⭐⭐⭐⭐ Good Quality Epoxy
*by H***S on 14 June 2026*

Very strong long open epoxy, I needed to set some knife blanks into wooden handles and this worked very well when left overnight to cure. Easy to mix up in small amounts and dries with a very clean finish, any excess is easy enough to wipe away when applying.
